Used Fluval C4 HOB Filter
I have a used Fluval C4 HOB Filter rated for 70Gal from storage, a little too strong for my 5gal even turning it all the way down, and the intake is a little too long, so I would rather not to cut it, currently replaced it with a AQ20. Looking to get $30. A little noise as you would expect for any used hob filter. The upper compartment came with some bio media but I will keep them as I am cycling my tank with this filter atm but I will replace them with eheim biomedia to fill that compartment. The bottom compartment is used for carbon but you can fill it with extra bio media or floss.
